| A German chemist, DR.. KosmaDn,
recommends the use of treacle for form
J ing small coal and fine ore into solid
briquettes of fuel. A mixture of TO l.
per cent. of treacle is sufficient to make
coal-dust of lean Silesian coal into good
solid blocks, giving stroag coke. Such
| blocks are good for gss-making. In the
same way such blocks Can be made OF
some powdery iron ores, for example, the
magnetic ores and pyri.e residues, before
| being reduced.
A raw material called bisso, or golden
wool, obtained from the Pinra nobilis, q
moliusca or shell-fish which attaches it.
self to the sea-bottom by a tuft of fibrous
hair, is utilized on the coast of Sardinia,
and especially the island Ct Madalena,
for making cravats, shawls and so on.
The ti0er Is of yellow brown color and
is collected by kind of iron rake. The
tuft is washed, dried, combed and spun,
then woven into cloth. The dark rich
''old gold" variety is most priced, and,
hes dts being pretty, is SAID 10 be dura-
bic.
The meaning of the candle-pOwer of q
light is accomplished by comparing the
shadow cast by rod in the light OF q
standard candle with the shadow cast by
the light to be tested. BY moving the
later toward or away from the rod q
point will De reached at which the shadow
cast by both lights will be he same
iHtensi y The intensity OF the twolights
is directly proportional TO the squares of
their distances from the shadows, /. e.,
suppose the light to be tested is three
times the distance of the candle, its
illuminating power is nine times as great.
If it were possible to raise above the
atmosphere which surrounds the earth
we should see nothing but an intense and
sharply defined ball of fire, while every
thing else would be wrapped in total
darkness. There could be no diffusion
of light without an atmosphere or some
similar medium for it to act upon; but if
the air around US extended to q height OF
700 miles the rays OF the sun could not
penetrate it, and we would be left in
darkness. At the depth of 700 feet in the
ocean the light ceases altogether, one
half of the light being absorbed il pass
ing through seven feet of the puresG
water,
An enterprising German firm is building
up q large business in the manufacture of
liquid carbonic acid, which, though so re-
Gently only scientific curiosity, is now
in extensive demand for industrial puc-
poses. II is used for charging beer in
the cssk, in the manufacture of settler
waters, and for fire eXtinguishers. By its
expansion the Krupps of Essen subject
their great castings to the enormous
pressure Of 1900 atmospheres. rs gas is
also expected 10 prove valuable for in
ti4ting balloons to raise sunken ships,
heavy weights having been very quickly
raised from the sea bottom by its aid
A German chemist has invented new
kind of au;pSthetic bullet which, he urges
will, if brought into general use, greatly
diminish the horrors of war. The bullet
is of a brittle substance, breaking di
reCtly when it comes in contact with the
object at which it is aimed. 1t contains
powerful an9Sthetic, producing instanta-
neously complete insensihility, lasting
twelve hours, which, except that the &C
ton of the heart continues, is not to be
distinguished from death. A battle field
where these bullets are used will in q
short time be apparently covered with
dead bodies, but in reality merely with
the PROSTATE forms of soldiers reduced
for the time being to state unconscious
ness. While in this condition they may, the
German chemist points out, be packed in
ambulance wagons and carried off as
prisoners.
1t is reported by the Berlin Eisenzei-
tung that the new process for making
steel pipe employed at Burbach is very
successful. A syndicate has been formed
to build works at Burbach, the capital
being ,200,00) marks, of which 100000
marks are issued to the patentee, A. Man
nesmanne of Remschidt. 1t is stated that
Funke & Ebers of Hagar, Germany, have
also purchased patent rights, and large
firm in Paris proposes to apply the
method to the manufacture of copper tub
ing. As to the process: As soon as the
steel is cast into the round mold core
is thrust in the steel so that tube is
formed between il and the walls of the
mold. In order to prevent cracking of
this annular casting during cooling the
core is so made that 1t follows up the
shrinkage of the steel. The steel cup
thus obtained may then be rolled in an
ordinary train.
A well known man OF Boston, after FIX
perlmenting for fifty years, claims that he
has discovered q me allie composition
capable of completely cutting eff magnet
ic attraction. A Boston Globe reporter
called upon the gentleman the other day
and witnessed number of very interest
irg experiments which prove that the in
ventlon is al that is claimed. One OF the
shown was with very sensi- |
tive compass and a very powerful mag
net. The plate was placed between the
and magnet, and no perceptible
passed through the interVeu
ing composition, but on removing
the composition the needle of the COM
pass was Immediately affected in de-
cided manner. A series of other tests
were given equally satisfactory, confirm |
ing the peculiar power of the compost |
ton. The inventor has thoroughly tried
every conceivable variety of other ingre-
dents, and in each the needle was vlsibly
affected. These facts may show that
can be controlled, and the in
7entor claims that this opens a new
source of motor power in which con-
Yenience and economy are combined.
